Method for adjusting and for displaying the adjustment of a camera lens

Abstract

A method for adjusting and for displaying the adjustment of a camera lens, in particular for adjusting the image sharpness (focus) of a camera lens for analog or digital motion picture cameras, comprising a scale shiftable relative to the display of a current adjustment value and coupled with an adjusting device. On the scale the adjustment values are represented numerically and/or as graphical symbols. A scale range bordering on the current adjustment value is located in a display window. At least one adjustment value is highlighted by a marking and a marking located outside the display window is displayed at the edge of the scale.

         19 . A method for adjusting and for displaying the adjustment of a camera lens, in particular for adjusting the image sharpness (focus) of a camera lens for analog or digital motion picture cameras, comprising a scale shiftable relative to the display of a current adjustment value and coupled with an adjusting device, on which scale the adjustment values are represented numerically and/or as graphical symbols, and of which a scale range bordering on the current adjustment value is located in a display window, wherein at least one adjustment value is highlighted by a marking and a marking located outside the display window is displayed at the edge of the scale. 
     
     
         20 . The method according to  claim 19 , wherein the marking located outside the display window is displayed at the end of the scale at which it would be located on a virtually expanded scale. 
     
     
         21 . The method according to  claim 19 , wherein the marking located outside the display window is represented vertical to the orientation of the scale and its distance to the scale is indicated in dependence on how far outside the virtually expanded scale the respective marking is located. 
     
     
         22 . The method according to  claim 19 , wherein a plurality of adjustment values are represented by markings with different symbols and/or colors and/or alphanumeric characters. 
     
     
         23 . The method according to  claims 21 , wherein markings for adjustment values which are located outside the display window are represented vertical to the orientation of the scale, wherein the distance of the respective marking from the scale depends on how far outside the display window the respective marking is located in dependence on the current adjustment value. 
     
     
         24 . The method according to  claim 23 , wherein proceeding from the scale the markings located outside the display window are represented vertical to the scale in the order of the increasing or decreasing adjustment values. 
     
     
         25 . The method according to  claim 19 , the markings located inside the display window are represented with larger symbols and/or alphanumeric characters beside their associated adjustment value than the markings located outside the display window. 
     
     
         26 . The method according to  claim 19 , wherein the markings located inside the display window move along with the shifting of the scale and the markings leaving the display window at the respective end of the scale are shifted into display regions extending vertical to the longitudinal orientation of the scale, wherein the distance of the respective marking from the scale depends on how far outside the display window the respective marking is located with respect to the current adjustment value. 
     
     
         27 . The method according to  claim 19 , wherein the markings are set by entering the adjustment values associated to the markings into an operating unit. 
     
     
         28 . The method according to  claim 19 , wherein the markings with their different symbols and/or colors and/or alphanumeric characters in conjunction with their associated adjustment values are additionally represented in a marking table beside the scale. 
     
     
         29 . The method according to  claim 28 , wherein the order of the markings and associated adjustment values represented in the marking table corresponds to the order on the scale. 
     
     
         30 . The method according to  claim 19 , wherein the current adjustment value is indicated by a graphical symbol which substantially is located in the middle of the display window. 
     
     
         31 . The method according to  claim 30 , wherein the graphical symbol indicating the current adjustment value covers the scale. 
     
     
         32 . The method according to  claim 30 , wherein the current adjustment value is shown enlarged as an alphanumeric character in a window faded in. 
     
     
         33 . The method according to  claim 19 , wherein adjustment values for the image sharpness (focus) are represented on the scale and parallel to the orientation of the scale adjustment values for the iris opening of the camera lens are represented and that the current adjustment values such as image sharpness and iris opening are shown enlarged as alphanumeric characters in windows faded in, which alphanumeric characters are aligned with the graphical symbol indicating the current adjustment value. 
     
     
         34 . An apparatus for carrying out the method according to  claim 19 , comprising at least one focus drive unit, zoom drive unit and iris drive unit, an operating unit connected with the focus drive unit, zoom drive unit and iris drive unit via an electric line or via a radio link, which contains a display window with adjustment values represented as numerical and/or graphical symbols in a scale range, a means for entering markings for selected adjustment values, a means for selecting entered markings and a control means actuating the display window and outputting control signals for selecting the markings to the focus drive unit, zoom drive unit and iris drive unit. 
     
     
         35 . The apparatus according to  claim 34 , wherein the focus drive unit, zoom drive unit and iris drive unit are coupled with an associated lens ring of the camera lens, receive data on the image sharpness, zoom and iris adjustment of the camera lens and drive the lens rings of the camera lens for adjusting desired values of the image sharpness, zoom and iris adjustment of the camera lens. 
     
     
         36 . The apparatus according to  claim 35 , wherein the focus drive unit zoom drive unit and iris drive unit output detection signals of the actual values of the image sharpness, the zoom adjustment and the iris adjustment to the motion picture camera or a camera-side control and detection unit and receive desired values for the image sharpness, zoom adjustment and iris adjustment from the motion picture camera or the control and detection unit.
